Evan has a summer job to pick berries on a farm. he earns $2.00 every 15 minutes that he picks strawberries. he earns $2.40 for every 15 minutes that he picks blueberries. he picked strawberries for an hour and blueberries for 45 minutes. how much money did evan earn?

From the concluding part of the question, it may be inferred that If he picked strawberry for an hour that means he picked strawberry for 60 minutes. Okay so for 15 minutes he earned $2 Then in 60 minutes he will earn X So 15 * X = 2 * 60 Then it follows that X = 120/15 = $8 On the other hand if he earns $2.40 for 15 minutes picking blueberry Then it follows that he earned $X in 45 minutes. Also X * 15 = 2.4 * 45 X = (2.4 * 45) / 15 = $7.2 So he earned $7.2 + $8 = $15.2 So
